Biological alarm device for moisture content monitoring

The invention discloses a biological alarm device for moisture content monitoring, which belongs to the technical field of forest monitoring and comprises an L-shaped mounting plate, and a support is arranged at the bottom of the L-shaped mounting plate. According to the invention, a water bear worm culture dish is arranged in the observation cylinder, and a monitoring alarm mechanism composed of an optical microscope, a high-definition camera, an image processing module, a data processing and control unit and a wireless alarm is arranged, so that the form of water bear worms can be observed in the use process; the water bear worms can show specific behavior and form changes in environments with different water contents, the data processing and control unit compares the data with a preset normal water content range, when the water content exceeds the normal range, the behavior and form of the water bear worms can correspondingly change, meanwhile, the humidity data can be abnormal, and at the moment, the wate
